What is the VB Equivalent of the following C# boolean expression?
data.GetType() == typeof(System.Data.DataView)
Note: The variable data is declared as IEnumerable.
When we have new in C#, that personally I see only as a workaround to override a property that does not have a virtual/overridable declaration, in VB.NET we have two "concepts" Shadows and Overloads.
In which case prefer one to another?

if I have a small double in vb.net
e.g. dim x as double = 0.00000003
a conversion to a string would produce a E-presentation (3E-7). in debugging the value it will be shown as full number (0.00000003).
how can I get the full number in a string?
thanks!

Hey guys and gals,
Any one knows of an easy to use/well documented Facebook library for VB.NET?
I have searched the Interwebs for it for a long time and even the official one has a very poor documentation for beginners. It looks like you have to be a Facebook developer to work with them.
Any help is much appreciated.
Thanks!
